I leave the organizer in it's original packaging in the suitcase. Because, Then it's totally compacted and as flat as it's going to get. Then transfer all the stuff when I get onboard.
El biggo mistake I made on my first organizer cruise, I left it behind. I thougt it would be so easy to pick up another one at the $1.00 store. But now they are more difficult to find. I ended up replacing it for $6.00 at Target.
